Woodlake Municipal Code Ch. 13.08 Cross-Connections

The definitions attached to the ordinance codified in this chapter and noted as "Appendix A" are made a part of this chapter as though they were repeated herein.

(Ord. 468 § 2 Art. 1, 1992)

The following rules and regulations concerning cross-connections to the water system of the city are adopted, and all work in respect thereto shall be performed as herein required and not otherwise.

(Ord. 468 § 2 Art. 2-01, 1992)

The purpose of this chapter is:

A. To protect the public potable water supply of the city from the possibility of contamination or pollution by isolating within the user's internal distribution system or the user's private water system such contaminants or pollutants which could backflow into the public water system;

B. To promote the elimination or control of existing cross-connections, actual or potential, between the user's in-plant potable water system and nonpotable water system, plumbing fixtures and industrial piping systems; and

C. To provide for the maintenance of a continuing program of cross-connection control which will systematically and effectively prevent the contamination or pollution of the city's water system.

(Ord. 468 § 2 Art. 2-02, 1992)

The city council shall be responsible for the protection of the water system from contamination or pollution due to the backflow of contaminants or pollutants through a water service connection. If, in the judgment of the council, an approved backflow prevention assembly is required for the safety of the water system, the council, or its designated agent, shall give notice in writing to the user to install such an approved backflow prevention assembly at such specific locations on his premises. The user shall immediately install such approved assemblies at the user's own expense. Failure, refusal or inability on the part of the user to install, have tested and maintain the assemblies shall constitute grounds for discontinuing water service to the premises until such requirements have been satisfactorily met.

(Ord. 468 § 2 Art. 2-03, 1992)

This chapter shall be known as the "cross connection ordinance of the city of Woodlake."

(Ord. 468 § 2 Art. 2-04, 1992)

Protection of the public water system at the service connection shall include, but not be limited to the following:

A. Each public water service connection supplying water to premises having an auxiliary water supply shall be protected against backflow of water from the premises into the public water system by the proper installation of an approved method of backflow protection;

B. Each public water service connection supplying water to premises on which any substance is or may be handled in such a fashion as to permit introduction into the water system shall be protected against-backflow of the substance into the public water system. This shall include the handling of process waters and waters originating from the public water system which have been subjected to deterioration in bacteriological and/or chemical quality; and

C. Approved backflow protection measures shall be initiated on the service connection from the public water system to any premises that has a cross-connection.

(Ord. 468 § 2 Art. 3-01, 1992)

Protection of potable water systems within the user premises shall include, but not be limited to, the following:

A. Plumbing Connections. Where the circumstances are such that there is danger to health from the backflow of sewage, as from sewers, toilets, hospital bedpans and the like, into a drinking water system, a dependable form of backflow protection shall be installed to prevent such backflow.

Devices suited to the purpose of avoiding backsiphonage from plumbing fixtures are roof tanks or separate pressure systems which are separately piped to supply such fixtures, recognized approved vacuum or siphon breakers and other backflow protective devices which have been proved by appropriate testing laboratories to be dependable for destroying the vacuum.

More specifically, plumbing connections shall comply with the provisions of the most recent edition of the Uniform Plumbing Code.

B. Separate Drinking Water Systems. Whenever the city determines that it is not reasonably possible to protect the water system against entry of water from a source or piping system on user premises, or equipment is proposed which cannot be approved as safe or resulting in a water supply which is potable for human use, an entirely separate drinking water system shall be installed.

C. Fire Systems.

1. Water systems for fighting fires, derived from a supply and/or source that cannot be approved as safe or potable for human use shall be kept wholly separate from drinking water pipelines and equipment. In cases where the domestic water system is or may be used for fire fighting purposes, an approved form of backflow protection shall be installed to protect such individual drinking water lines as are not used for fire fighting purposes. In no instance shall the domestic water piping be utilized to carry nonpotable water for fire fighting purposes.

When disinfection of an auxiliary water supply is depended upon to render the water safe, the means of applying the disinfectant under this regulation shall be automatic with operation of the pump or pumps employed with the dangerous water in question. Adequate supplies of chlorine and its compounds must be kept on hand at all times. Chlorine dosing equipment shall be tested daily and kept in good operating condition.

The public water supply must be protected against backflow from such domestic fire systems as detailed in Sections 13.08.080 and 13.08.090; and

2. An approved form of backflow protection shall be provided on the public water service connection supplying water to automatic fire extinguishing systems.

D. Process Waters. Potable water pipelines connected to equipment for industrial processes or operations shall be disconnected therefrom if practicable. Where disconnection is not practicable, a suitable form of backflow protection located beyond the last point from which drinking water may be taken shall be provided on the feed line to process piping or equipment. In the event the particular process liquid is especially corrosive or apt to prevent reliable action of the backflow prevention device, an approved air-gap separation shall be provided.

E. Sewage Treatment Plants and Pumping Stations. Sewage pumps shall not have priming connections directly connected to any drinking water system. No cross-connections shall exist between the drinking water system and any other piping, equipment, or tank in any sewage treatment or sewage pumping station.

F. Water Line Sizing. Inasmuch as many serious plumbing hazards are due to undersized piping, water supply piping which is too small, thereby causing vacuum conditions when fixtures are flushed or water is drawn from the system in other ways, shall be enlarged whenever possible.

(Ord. 468 § 2 Art. 3-02, 1992)

The specific type of approved backflow protection (air-gap separation, reduced pressure principle backflow prevention device, double check valve assembly or pressure type vacuum breaker) required shall depend on the degree of hazard involved. This shall include, but not be limited to, the following criteria.

A. An approved air-gap separation shall be used where there is a health hazard, system hazard, contamination hazard or a plumbing hazard which cannot be presently eliminated. The air-gap separation shall be located on the user's side of and as close to the service connection as is practicable. All water piping from the service connection to the air-gap separation shall be above grade and entirely visible. If these conditions cannot reasonably be met, the public water supply may be protected by proper installation of an approved reduced pressure principle backflow prevention device, providing this alternative is acceptable to the city.

B. An approved double check valve assembly shall be provided on the service connection to a premises on which there is an auxiliary water supply handled in a separate piping system with no known cross-connection.

C. An approved air-gap separation or an approved reduced pressure principle backflow prevention device shall be provided at the service connection to a premise on which there is an auxiliary water supply where cross-connections exist which cannot be presently eliminated.

D. An approved air-gap separation shall be provided at the service connection to any sewage treatment plant, sewage pumping station or stormwater pumping station. If these conditions cannot be reasonably met, the public water supply may be protected by the proper installation of an approved reduced pressure principle backflow prevention device, provided this alternative is acceptable to the city. The final decisions in these matters shall rest with the State Department of Health Services.

E. Low head sewage lift stations on residential and commercial premises may be protected as follows:

1. Isolation of the pumping unit from the rest of the building, prohibition of water piping in the sewage pump room and installation of an approved double check valve assembly at the service connection; or

2. Industrialization of the water line into the sewage pump room area (if there must be water service in the area) by providing an approved reduced pressure principle backflow prevention device on the water line supplying the area. All hose connections and/or valved outlets beyond the device that may be used for drinking water shall be identified as "DANGER-UNSAFE WATER" or "UNSAFE WATER-NOT FOR DRINKING."

F. An approved air-gap separation shall be provided at the service connection to any premises on which any materials dangerous to health or toxic substance in toxic concentration is or may be handled under pressure. If these conditions cannot reasonably be met, the public water supply may be protected by the proper installation of an approved reduced pressure principle backflow prevention device, provided this alternative is acceptable to the city.

G. An approved double check valve assembly shall be provided at the service connection to a premises on which a substance that would be objectionable, but not necessarily hazardous to health is or may be handled in such a manner as to permit entry into the water system.

H. The minimum of an approved double check valve assembly shall be provided at the service connection to an automatic fire extinguishing system. All systems shall be reviewed to determine when more stringent backflow protection is justified.

I. An approved backflow prevention device as designated by the city shall be provided at the service connection to any premises on which the city determines that a special hazard exists. This shall include, but not be limited to, such premises where cross-connections have been eliminated, but where the water system is of such size and the water use so extensive and diversified that a high potential exists for creating cross-connections.

J. Internal backflow protection may be accepted in lieu of master protection, provided this alternative is acceptable to the city.

K. The following is a list of premise uses which generally require backflow protection for the public water service connection. The required type of backflow prevention device is indicated. Backflow protection requirements for premises not appearing on this list shall be discussed with the city.

NOTE:

Whenever a water service includes a combination of two or more usages, the usage with the most restrictive device shall control. An air gap is the most restrictive and a vacuum breaker is the least restrictive device.

DEVICE DEFINITIONS:
